I'm wondering if this is just me - or if this is a bigger issue with Slingshot.

I've been a slingshot customer for a very long time. I'm currently on Broadband 150 plan. I live arounf Titirangi / New Lynn border in Auckland.

For the past few months - I've noticed a considerable drop in my internet connection speeds. I have logged into my modem to see if I could spot anything - and it turns out that my ADSL sync speed is measly Data Rate Down/Up3289/1197(Kbps) Now, that surprised me somewhat, since I have always been getting ADSL sync rates in high 8000's, occasionally reaching 9000+ range.

I have restarted my router a few times (btw I'm using Belkin ADSL2+ Wireless G router with the latest firmware installed, average router - however never had an issue with it for the past 2 years). Unplugged all phones from the phonelines, bypassed the line filter - no noticeable improvement in the sync speed. I have also tried a Dynalink 1 port router (standard one that comes with new Slingshot connections) and that only did marginally better - coming in at low 4000's.

Now, one thing that comes to mind - is some time ago I have looked on a website to see the status of my local exchange - and there was an upgrade planned for Dec 2011 to take it up to ADSL 2+.

Has anyone experienced a similar situation? What is the best way to try and improve it? It is a bit unbearable at the moment...

Without knowing your exact details nobody is going to be able to give you a definitive answer - because only you will know the answers to the questions. My suggestion would be to read my blog post which should answer some of your questions.

Satanatas: Slingshot do not control the ADSL sync rates. Its most likely a line issue.

Very good chance it is caused by the rain lately.

The call centre should be able to log a fault for that.

Slingshot do in effect "control" the sync rate is the customer is still connected to ULL equipment in an exchange but is now served off a Chorus cabinet. If this is the case the customer need to be migrated back to a Chorus wholesale connection.

I have done some further investigation - on this page http://chorus.co.nz/service-availability-tool using address "1 Poturi Streams Ave, Titirangi, Auckland" It looks like the local cabinet was upgraded in October 2011 to ADSL 2+. It's also curious to see that a lot of neighbouring cabinets are now on VDSL2.

I haven't kept up with the latest developments in xDSL technologies. I also think I might have a house wide splitter installed - since the home is equipped with an alarm. Does the splitter/line filters need to be upgraded for ADSL 2+ (or VDSL2 for that matter)
